Prime, Perform, Recover

This thesis examines the formal and conceptual framework of my artistic practice as it culminated in the installation of my thesis exhibition, Prime, Perform, Recover. My exhibition seeks to operate as an analysis and critique of the separation inherent in media presentation and rhetoric surrounding natural disasters. I utilize the aesthetics and vocabulary of disaster capitalism and prepping culture in order to pose direct questions about ecological and social change. I examine the role of images within mass media image production as an all encompassing Now-Time. In this paper I describe frameworks that my practice proposes as potential solutions to these problems, and I position my research in the context of artists and artworks that have influenced me and operate within similar channels as my own

Recollected in tranquility : FE teachers’ perceptions of their initial teacher training

"The main research question posed by the project was: ‘What are FE teachers’ perceptions of the effectiveness of initial training in helping them to teach and to support learning?’" -- page 1

On acoustic cavitation of slightly subcritical bubbles

The classical Blake threshold indicates the onset of quasistatic evolution leading to cavitation for gas bubbles in liquids. When the mean pressure in the liquid is reduced to a value below the vapor pressure, the Blake analysis identifies a critical radius which separates quasistatically stable bubbles from those which would cavitate. In this work, we analyze the cavitation threshold for radially symmetric bubbles whose radii are slightly less than the Blake critical radius, in the presence of time-periodic acoustic pressure fields. A distinguished limit equation is derived that predicts the threshold for cavitation for a wide range of liquid viscosities and forcing frequencies. This equation also yields frequency-amplitude response curves. Moreover, for fixed liquid viscosity, our study identifies the frequency that yields the minimal forcing amplitude sufficient to initiate cavitation. Numerical simulations of the full Rayleigh-Plesset equation confirm the accuracy of these predictions. Finally, the implications of these findings for acoustic pressure fields that consist of two frequencies will be discussed.Comment: 14 pages, Presented at APS/DFD conference in Philadelphia 199

What checkers actually check: an eye tracking study of inhibitory control and working memory

<p>Background - Not only is compulsive checking the most common symptom in Obsessive Compulsive Disorder (OCD) with an estimated prevalence of 50–80% in patients, but approximately ~15% of the general population reveal subclinical checking tendencies that impact negatively on their performance in daily activities. Therefore, it is critical to understand how checking affects attention and memory in clinical as well as subclinical checkers. Eye fixations are commonly used as indicators for the distribution of attention but research in OCD has revealed mixed results at best.</p> <p>Methodology/Principal Finding - Here we report atypical eye movement patterns in subclinical checkers during an ecologically valid working memory (WM) manipulation. Our key manipulation was to present an intermediate probe during the delay period of the memory task, explicitly asking for the location of a letter, which, however, had not been part of the encoding set (i.e., misleading participants). Using eye movement measures we now provide evidence that high checkers’ inhibitory impairments for misleading information results in them checking the contents of WM in an atypical manner. Checkers fixate more often and for longer when misleading information is presented than non-checkers. Specifically, checkers spend more time checking stimulus locations as well as locations that had actually been empty during encoding.</p> <p>Conclusions/Significance - We conclude that these atypical eye movement patterns directly reflect internal checking of memory contents and we discuss the implications of our findings for the interpretation of behavioural and neuropsychological data. In addition our results highlight the importance of ecologically valid methodology for revealing the impact of detrimental attention and memory checking on eye movement patterns.</p&gt

PCR analysis of the mouse mitochondrial genome to assess whether deletions accumulate with age

Overall aim was to determine if the accumulation of deleted mtDNA molecules in tissues during the normal aging process is confined to the human, or whether it is a phenomenon also shared by other species. The aging mouse was selected as an experimental model.Thesis (M.Sc.) -- University of Adelaide, Dept. of Clinical and Experimental Pharmacology, 199
